Having played both BOTW amd The Witcher 3, I have to say that BOTW is franchise re-defining, while Witcher 3 is one of the defining titles if the current generation.

Both are great in different areas of their design, but I feel The Witcher 3 was more content packed and offered diversity, with every aspect fully fleshed out and intricate. So it left a bigger impact on me than BOtW, overall.

But there are aspects of BOTW’s gameplay that beat those found in The Witcher 3. But taken as a whole, the latter is simply more fully fleshed out and content/feature packed.

Out of curiousity what would you say are other games that are "generation defining"?

I have played a lot of great games this gen, but other than the Witcher 3 I have not played a game that are truly, how do I say it, let's say exponentially high quality and truly masterful. I have yet to play GoW however and RDR is around the corner.

Horizon was great, but not truly mind boggling amazing. Farcry 4 as well. Bloodborne was amazing too, but TW3 feels like it's just a tier above. Uncharted 4 as well. If it had better pacing maybe it would have reached that level. But I'm curious to hear your thoughts
